No special cleaning instructions. I'd stay away from a "grease rag" and "Rem Oil". For lubrication, I'd use some type of "CLP" product. My personal favorite is "Mil-tec".
The sights are sealed capsules. No need to worry about cleaning solvents damaging them. One thing you should be cautious about is "over lubricating". Check out the owner's manual to verify the lubrication points.
